Abstract
A coil electronic component according to an embodiment of the present invention includes a body including a coil pattern and a display portion formed on a surface of the body and having a base region and a marking region formed by a white pigment on a part of the base region As a result, it is possible to realize an excellent discriminating power in indicating the direction of the parts.
Description
The present invention relates to a coil electronic component.
An inductor is one of the components forming an electronic circuit together with a resistor and a condenser. The inductor is formed by winding or printing a coil on a ferrite core and forming electrodes at both ends. And is used as a component for forming an LC resonant circuit. The inductors can be classified into various types such as a laminated type, a wound type, and a thin type according to the shape of a coil.
In the case of the inductor, it is necessary to distinguish between the upper and lower parts because the capacitance value varies according to the direction of the inner coil. For this purpose, a process for marking the display part on the surface of the part is required. In recent years, the size of the parts tends to become smaller in the trend of miniaturization and multifunctionality of electronic products, and such a marking area also becomes smaller. When the marking area is reduced, it is difficult to identify the display part, which causes problems such as a decrease in the part yield and an increase in the processing time.
Thus, in the art, attempts have been made to improve the discrimination of the markings marked on the surface of the inductor, which is more necessary when the size of the parts is small. In this connection, the present invention intends to provide a coiled electronic part having a display part with excellent discrimination as one object.
According to one aspect of the present invention, there is provided a method of manufacturing a coiled electronic component, the method including the steps of: forming a body including a coil pattern on a surface of the body; And a display portion having a marking region formed by a white pigment on a part of the base region.
In this case, the marking region may be formed to fill the groove formed on the upper surface of the base region.
In addition, the white pigment may be typically TiO 2 , and the marking region may be formed by a paste printed on the substrate region.
In addition, since white pigment particles exist in a dense form, excellent discrimination power can be realized, so that the TiO 2 powder contained in the paste may have a BET of 5.0 m 2 / g or more. Further, the TiO 2 powder included in the paste may contain about 20-22%.
By using the coil electronic component proposed in the embodiment of the present invention, the discrimination power of the display portion marked on the surface can be remarkably improved, leading to an improvement in the process efficiency with respect to the coil electronic component.

Fig. 4 illustrates various forms of marking areas that can be employed in the embodiment of Fig.

Hereinafter, embodiments of the present invention will be described with reference to specific embodiments and the accompanying drawings. However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below. Further, the embodiments of the present invention are provided for a more complete description of the present invention to the ordinary artisan. Accordingly, the shapes and sizes of the elements in the drawings may be exaggerated for clarity of description, and the elements denoted by the same reference numerals in the drawings are the same elements.
It is to be understood that, although the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Will be described using the symbols. Further, throughout the specification, when an element is referred to as "including" an element, it means that the element may include other elements as well, without departing from the other elements unless specifically stated otherwise.

The base region B is made of a darker material than the marking region M and can be black as shown in FIG. In this case, white and black are complementary color contrast, which can provide excellent discrimination power. The base region B may include the same magnetic material as the
As described above, the marking portion M is formed by a white pigment, and TiO 2 can be used as an example of such a white pigment. 3, the marking region M may be formed so as to fill the groove formed on the upper surface of the base region B, and further, the upper surface of the marking region M and the upper surface of the base region B May be formed as a co-plane.
As an example of the method of obtaining the shape shown in FIG. 3, a white pigment may be paste printed on the base region B, but pressure may be applied to the base region B in this process. In this case, the paste for printing the white pigment may include TiO 2 powder and glass, wherein the glass is added for the purpose of connecting TiO 2 powder during the sintering process because TiO 2 has a relatively high sintering temperature . The white pigment remaining after sintering in the paste for forming the marking area M needs to be left in a sufficient amount in order to secure discrimination power. In this case, a white pigment type marking area M having excellent discoloring power could be obtained when about 20 to 22% of the TiO 2 powder was contained in the paste component and about 150% of the glass was added to the TiO 2 powder.
It is possible to expect an improvement in efficiency in the process of mounting the coiled

This high cyan marking area M can be realized by forming a dense intergranular connection structure after sintering using a white pigment powder having a relatively small particle size. This will be described with reference to FIGS. 5 and 6. FIG. Fig. 5 schematically shows the behavior of light incident on the marked region when the white pigment is not densely formed and when the white pigment is densely formed. As shown in FIG. 5, when the white pigment particles are not arranged densely (on the left side), the amount of light scattered or absorbed increases, so that the discrimination power of the marked region is remarkably lowered. In contrast, when the white pigment is densely formed, most of the light is reflected, and thus the cyanation can be greatly improved.
In this connection, Fig. 6 schematically shows the sintering behavior of the white pigment powder having different particle sizes. 6, when the particle size is relatively large (upper part in FIG. 6), the size of the pores formed between the particles is large even after the sintering, so that it is difficult to obtain a dense particle connection structure. In contrast, when the size of the particles is relatively small (lower part of FIG. 6), fine pores remain after the sintering, which is a level that does not significantly affect the discrimination power.
The inventors of the present invention have experimented in terms of the specific surface area (BET) of the white pigment, that is, the TiO 2 powder, which is capable of sufficiently securing white coloration based on the above idea. When the BET of the TiO 2 powder is 5.0 m 2 / g, it was confirmed that a dense particle connection structure without deterioration of discrimination power could be obtained.
As described above, in the case of the coil electronic component proposed in one embodiment of the present invention, since the connectivity of the color pigment particles is realized in a remarkably dense state, it is possible to provide a display portion having excellent discrimination power, The associated process efficiency can be greatly improved.
The present invention is not limited to the above-described embodiments and the accompanying drawings, but is intended to be limited only by the appended claims. It will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. something to do.
